    Google adopts small nuclear power reactors at unprecedented scale — inks deal for seven reactors to feed AI data centers

  • I'm more worried that after splurging on EVs now we don't go through with the act that actually makes a difference. After all we've already got the personal social reward of doing "the right thing tm". We can party and forget the climate doomerism my new Tesla saved the world, yay ! Personal responsibility and the free market has prevailed !

  • A few percentage points reduction in co2 emission isn't going to move the needle. The whole grid has to shutdown fossil fuel energy production for this transition to make sense.

  • fossil fuel power plant are tops 40% efficient while ice powered cars are around 33%.

    If you power you EV off a fossil fuel power plant, then that difference, minus the grid losses, the charging losses and then the inverter and motor losses, is how much co2 emissions you are saving.

    Of course that's assuming your driving habits don't change, with that high upfront investment and relatively lower per mile costs compared to using gasoline.

    And that's not to mention the one time emission from the production of that EV amortised on its 15 year hoped-for lifetime.

    Beside capturing government subsidies and the arbitrage saving from using temporarily cheaper electricity as fuel, I don't see EVs making much sense either from an economic or a saving the planet standpoint.

    Without a zero emission energy production as the source, EVs don't make sense beyond hype and cope.

    All fossil fuel electrical generation, and that includes natural gas, has to be shutdown. Or else it will not make a lick of difference.

  • That is nowhere near enough. It's 33% versus 40% difference between co2/kWh . we need zero co2/kWh or else it's all a waste of time.

    It's only acceptable if we are transitioning to zero emission grid. If we stay on natural gas then it won't even move the needle.

  • No , if you run EVs off a grid fossil fuel generator, that's the difference between 33% and 40% efficient. It's not enough to move the needle. It doesn't even pay for itself in terms of emissions.

    The energy source absolutely has to be ZERO emissions as well. If not then it's just climate cope.

  • Fossil fuel power plants don't count. EVs running of fossil fuel make no sense. Remove them from the equation and my prediction becomes extremely optimistic.

  • No, EVs alone require 10 times the current installed energy production. We're not even close. Expect energy rates to quadruple. The price will increase until people can't afford the commute with their entire day's paycheck.

  • The high price of nuclear power comes from it being a stagnant and obsolete technology for 30 years.

    As well as being choked to death in red tape.

  • How ham radio endures - and remains a disaster lifeline - in the iPhone era

    Jump

  • On the other hand. Actual ham radio needs exotic and antiquated equipment, and for all of that you will get a clunky walkie-talkie that can't do the walkie part and has extremely limited bandwidth, that would collapse if even 0.1% of the population tried using it.

    If you do have all the gear and license and just tried to find how to send even 2400 bits per second to another ham radio operator, it would take weeks just to find one another and setup this feat of engineering.

    Modulations are obsolete, not even QAM64. There has been no attempt beam forming on HF so there is only very few channels that can be used concurently.

    All in all it's like CB but with extra steps.

    A hobby, not a reliable, practical method of mass communication and very stuck in its ways where preserving the spectrum is more valued than communication.
